以下结合本说明书的附图，对本公开的较佳实施方式予以进一步地详尽阐述。
本公开实施例提出一种无线充电模块。该无线充电模块可以独立使用，为电子设备进行无线充电，也可以嵌入至其他的装置、设备、或支架内。在一示例中，该无线充电模块设于一平面的一侧，可以设置在平面的下侧，或当该平面沿竖直方向延伸时，无线充电模块可以设置在该平面的左侧或右侧。
上述平面可以是桌面、或台面、或是壁面等。在下述实施例中，以该无线充电模块应用于无线充电桌内为例进行说明。
请参阅图1，图1是根据一实施例示出的无线充电桌的侧视图。在一实施例中，无线充电座可以包括桌体21、设置在桌体21顶部的桌面22、以及无线充电模块，桌面22与桌体21能够围合形成有容置位23，无线充电模块容置于容置位23内。图2中，桌体21包括四条桌腿，桌体21还包括支撑板211，支撑板211与桌面22之间形成有用于容置无线充电模块的容置腔。无线充电模块中的部分可以固定设置在支撑板211上。在桌面22的某一区域可以划分为无线充电区域，无线充电模块可以对应设置于该无线充电区域下侧，具体可以位于无线充电区域的正投影处。当将可无线充电的电子设备放置于该无线充电区域内时，无线充电模块能够为电子设备充电。
在下述实施例中，将对无线充电模块的实施例进行说明。请参阅图2，图2是根据一实施例示出的无线充电桌的侧视图。
在一实施例中，无线充电模块包括控制电路11、检测板12、无线充电底座13、移动机构14。检测板12对应于桌面22设置，检测板12包括基板121以及分布于基板121上的多个磁性传感器122，多个磁性传感器122均与控制电路11电连接；磁性传感器122用于检测待充电设备放置于桌面上的位置；无线充电底座13设于检测板12背离桌面22的一侧；无线充电底座13用于对待充电设备进行无线充电；移动机构14与控制电路11电连接，控制电路11用于根据多个磁性传感器122所检测到的待充电设备放置于基板121上的位置控制移动机构14工作，以使移动机构14带动无线充电底座13移动至与待充电设备对应的位置处。
控制电路11在此可以是单片机、MCU、CPU或是控制芯片。在此以单片机为例说明。单片机上有各种I/O口可以供磁性传感器122以及移动机构14电连接。
在一示例中，检测板12放置在桌面22下，检测板12可以与桌面22具 有一定的距离。检测板12包括基板121以及设置在基板121上的多个磁性传感器122。基板121在此可以为PCB板。基板121可以是一整块PCB板，也可以是通过多块PCB板组合而成。
磁性传感器122可以是能够对磁场变化做出反应的磁阻传感器，霍尔传感器等。在一示例中，为了提高检测待充电设备的位置的准确性，采用的是磁阻传感器。
本实施例方案采用的磁性传感器122能够高效的确定待充电设备内无线接收线圈位置，可从而以节省无线充电底座13遍历检测接收线圈位置的时间，避免了在找寻最佳充电位置时产生多余热能影响无线充电底座13的稳定性。并且通过物理的方式确定出接收线圈的位置，可以避免使用软件算法来处理无线充电过程中的反馈信号，降低了算法处理错误的风险；因此本实施例方案在确定充电位置时，不需要在无线充电底座13、待充电设备进行通信，无需占用通信信道，节省了待充电设备以及无线充电模块的通信资源。
具体在工作时，在待充电设备上可以套设皮套，在皮套上设置一个或多个磁性件。当设置多个磁性件时，多个磁性件可以对应待充电设备的四个边角设置；当设置一个磁性件时，该磁性件可以对应于待充电设备的中心或接收线圈的位置进行设置。
当待充电设备放置在桌面22上时，桌面22下检测板12上对应磁性件的位置的磁性传感器122感应到磁性件时，磁性传感器122输出端所输出的电平会出现翻转，翻转的电平被控制电路11检测到，从而检测出磁性件所在的位置。
请参阅图3，图3是根据一实施例示出的检测板12的部分结构俯视图。磁性件在基板121上的排布可以均匀的，也可以是不均匀的。在一实施例中，为了提高检测待充电设备放置位置的准确性，设置多个磁性传感器122呈阵列排列于基板121上。
在一示例中，在沿横向方向，相邻两磁性传感器122间隔2cm排布，在沿纵向方向，相邻两磁性传感器122也间隔2cm排布。当充电平面长宽为350mm×350mm时，则需要17×17个磁性传感器122。
当单片机的I/O口数量足够时，可以使所有磁性传感器122同时工作，所有磁性传感器122的输出端连接至单片机不同的I/O口上。在一实施例中， 当单片机的I/O口资源较少，或需要节省接口资源的情况下。可以采用以下分时处理方案。具体的，控制电路11与多个磁性传感器122之间的连接线路包括均与控制电路11电连接的多条电源线、多条接地线；磁性传感器122具有电源端、接地端以及输出端；电源线与每排磁性传感器122对应设置，接地线与每列磁性传感器122对应设置；每排磁性传感器122的电源端均连接于同一条电源线上，每列磁性传感器122的接地端均连接于同一条接地线上；磁性传感器122的接地端均与控制电路11电连接。
多个磁性传感器122排列呈阵列，对应于每一横排设置一电源线，对应于每一列设置一接地线。当需要指定的磁性传感器122工作的时候，可以将该指定的磁性传感器122对应行的电源线上电，对应列的接地线与地连通，以此来使该磁性传感器122继续工作。因此可以依次选通一个磁性传感器122工作，从而可以达到分时读取磁性传感器122检测结果的目的。
例如，首先通过对第一行的电源线上电，第一列的接地线接地，从而选中位于第一行中位于第一个的磁性传感器122工作，从而读取该磁性传感器122的电平翻转情况。然后，间隔10毫秒，对第一行的电源线上电，第二列的接地线接地，从而选中位于第一行中位于第二个的磁性传感器122工作……。可以依次使每一行的磁性传感器122依次上电，然后再使第二行的磁性传感器122依次上电，直至轮询完全部的磁性传感器122。
在该实施例中，控制电路11只需要控制电源线、接地线的工作情况即可以实现检测待充电设备位置的目的。为了进一步节省控制电路11控制接口的资源。在一实施例中，设置无线充电模块还包括移位缓存器123；控制电路11通过移位缓存器123与电源线、接地线电连接；移位缓存器123用于根据控制电路11发出的控制信号，以使多个磁性传感器122依次上电工作。可以采用移位缓存器123芯片，或其他一些具有移位缓存器123功能的芯片。
在一示例中，对于8×8个磁性传感器122，可以配置两个移位缓存器123，一个移位缓存器123对应控制电源线的上电，一个移位缓存器123对应控制接地线的接地。例如对于8位串行输入、并行输出的移位缓存器123，控制芯片通过一个端口向其输入串行信号，移位缓存器123并行输出8路信号，以相应控制对应8×8个磁性传感器122中的8个电源线的上电。控制芯片通过另一个端口向其输入串行信号，移位缓存器123并行输出8路信号，以相 应控制对应8×8个磁性传感器122中的8个接地线的接地。控制芯片的另一个端口用于与所有磁性传感器122的输出端连接，以分时依次读取各个磁性传感器122的电平。
上述实施例中控制电路11与磁性传感器122的电气连接方式，可以有效的节省控制电路11的接口资源，使得使用较少的接口就可以读取一定数量的磁性传感器122输出值，从而大大提升了设计的便利性。
在控制电路11根据磁性传感器122的检测结果确定待充电设备的位置后，控制电路11发送控制信号至移位机构，以控制移位机构需要移动的距离。移位机构用于承载无线充电底座13移动至合适的位置，以使无线充电底座13能够对准待充电设备，从而保证无线充电的有效进行。
移动机构14可以基于磁吸附原理，设置在检测板12背离无线充电底座13的一侧。也可以采用抓手机构，设置在检测板12与无线充电底座13之间。在一实施例中，所述移动机构14位于所述无线充电底座13背离所述检测板12的一侧，以承托所述无线充电底座。
请参阅图4和图5；图4是与图2对应的无线充电桌内的无线充电模块结构示意图；图5是图4的俯视图。在一实施例中，移动机构14包括驱动电路143，与驱动电路143电连接的第一驱动电机、第二驱动电机，以及第一导轨141，第二导轨142；驱动电路143与控制电路11电连接，以接收控制电路11发出的控制信号，并根据控制信号驱动第一驱动电机、第二驱动电机工作；第一导轨141设置在第二导轨142上，第一驱动电机用于驱动第一导轨141沿第二导轨142移动；无线充电底座13设置在第一导轨141上，第二驱动电机用于驱动无线充电底座13沿第二导轨142移动。
驱动电路143包括信号处理及放大电路，以对控制电路11发出的控制信号进行处理放大。经过驱动电路143处理后的信号能够驱动第一驱动电机、第二驱动电机运动。
第一导轨141、第二导轨142可以互成90°。对应于桌面22上的无线充电区域，第一导轨141和第二导轨142的位置以及长度设置应能够使无线充电底座13能够移动范围能大致覆盖无线充电区域。
在一示例中，第一导轨141可以固定设置在桌体21的支撑板211上，第一导轨141上可以设有与第二导轨142对应的滑动条，以使第一导轨141能 够沿第二导轨142滑动。第一驱动电机用于驱动第一导轨141滑动。
相似的，无线充电底座13上设有与第一导轨141对应的滑动条，以使无线充电底座13能够沿第一导轨141滑动。第二驱动电机用于驱动第一导轨141滑动。
在一实施例中，第一导轨为丝杆，无线充电底座13上具有供第一导轨141穿设，且与第一导轨141配合的螺纹孔；第一驱动电机通过驱动第一导轨141旋转，以使无线充电底座13沿第一导轨141移动。
并且，还可以设置第二导轨142为丝杆，移动机构14还包括导轨座，导轨座与第一导轨141固定连接，导轨座具有供第二导轨142穿设，且与第二导轨142配合的螺纹孔；第二驱动电机通过驱动第二导轨142转动，以使导轨座沿第二导轨142移动。
控制电路11在读取了磁性传感器122的检测结果后，会根据检测结果确定待充电设备的中心位置或接收线圈的位置。在一示例中，待充电设备的四个边角处设置磁性件，控制电路11根据待充电设备的四个边角处设置磁性件的位置结合预设的算法计算出待充电设备的中心位置或接收线圈所对应的坐标，再通过获取到当前无线充电底座13的坐标后，即可以确定出无线充电底座13需要移动的距离以及移动轨迹。
在一实施例中，控制电路11用于根据无线充电底座13所要移动至的位置，计算第一导轨141沿第二导轨142以第一预设速度移动的第一时长，以及计算无线充电底座13沿第二导轨142以第二预设速度移动的第二时长。
具体的，首先计算无线充电底座13所要移动至的位置横向坐标与无线充电底座13当前位置的横向坐标的差值，再利用该差值与第一预设速度的比值，从而计算出第一导轨141需要沿沿第二导轨142以第一预设速度移动的第一时长。进而计算无线充电底座13所要移动至的位置纵向坐标与无线充电底座13当前位置的纵向坐标的差值，再利用该差值与第二预设速度的比值，从而计算出第一导轨141需要沿第二导轨142以第二预设速度移动的第二时长。在此第一预设速度和第二预设速度可以为相同的值，也可以为不同的值。
在一实施例中，无线充电模块还可以包括供电单元15，无线充电模块还包括供电单元15，供电单元15与控制电路11、移动机构14、无线充电底座13电连接，以为控制电路11、移动机构14、无线充电底座13供电。
在一示例中，供电单元15可以具有供电接口以及电源处理电路。无线充电模块工作时，需要通过供电接口接入电源，并通过电源处理电路对电源处理后为控制电路11、移动机构14、无线充电底座13供电。
在另一示例中，供电单元15还可以包括电池，从而使得无线充电模块可以在不接入市电的情况下仍旧能够利用电池的电能对电子设备进行无线充电。
本公开技术方案利用磁性传感器122阵列检测待充电设备的位置，并通过移动机构14将无线充电底座13移动到与待充电设备对应的位置，从而可以提高无线充电底座13内的发射线圈和待充电设备内的接收线圈最的耦合程度，从而提升电磁场的耦合程度，提升电磁能量传输的效率，保证无线充电的稳定性。
并且，当发射线圈与待充电设备内的接收线圈的耦合程度较低时，会触发发射线圈提高发射功率，以保证接收线圈的接收功率，从而造成发射线圈的发射功率较大，温升较高，从而造成安全隐患。本公开中，由于无线充电底座13内的发射线圈和待充电设备内的接收线圈的耦合程度较高，因此能够在一定程度上降低发射线圈的功率和发热，提升待充电设备内接收线圈的接收效率，从而降低发射线圈和接收线圈的温升，提高了待充电设备的充电安全性，
并且，本公开通过双导轨，从而使无线充电底座13快速的达到最佳的充电位置，可以减少待充电设备因摆放偏位，重复向控制电路11发送功率请求指令而占用信道的问题，也可以避免FOD(异物检测)发生导致的充电失败或无法充电等问题。
综上，本公开技术方案能够提高无线充电的有效性以及安全性。
本公开还提出一种无线充电装置，无线充电装置包括收容盒，以及无线充电装置上述实施例中的所述的无线充电模块，所述无线充电模块收容于所述收容盒内。

在一实施例中，所述盒盖上设有安装部，所述安装部用于供所述盒体与 安装平面连接。安装部可以是固定在盒盖顶部的魔术贴。
在此安装平面可以是桌面、墙面、地面等，在此不做具体限定。
本公开还提出一种无线充电方法，在下述实施例中，将对无线充电方法进行说明。在此以该无线充电方法应用于上述无线充电模块中为例说明，可以理解的是，该无线充电方法不局限于应用于上述无线充电模块中。请参阅图6，图6是根据一实施例示出的无线充电方法一实施例的流程图。
在一实施例中，在基板121上设置多个磁性传感器122，磁性传感器122用于检测物体放置于基板121上的位置；
方法包括：

34，控制所述无线充电底座13对所述物体进行无线充电。
关于磁性传感器122的设置以及检测方案可以参照上述无线充电模块中相关的实施例。
在此，磁性传感器122能够感应到带有磁性件的物体。在一实施例中，为了使无线充电模块能够对可被充电的电子设备进行充电，保证无线充电的进行，在一实施例中，34，控制无线充电底座13对待充电设备进行无线充电的步骤之前，方法还包括：

当物体的属性与预设的属性匹配时，确定物体为可充电设备；
控制无线充电底座13对待充电设备进行无线充电，包括：
当物体为可充电设备时，控制无线充电底座13对待充电设备进行无线充电。
当物体为不可充电设备时，控制无线充电底座13不对待充电设备进行无线充电。
在一示例中，物体的属性可以分为两大类，一类是可充电设备，一类是不可充电设备。在此预设的属性可以是可充电设备具体类型，例如手机、充电宝、手表等。当物体与可充电设备具体类型之一匹配时，则确定物体为可 充电设备。
该实施例中的步骤可以在步骤34之前的执行。当在步骤34之前执行时，若确定物体为不可充电设备，则无需控制移位机构移动。
在另一实施例中，可以在移位机构带动无线充电底座13运动至物体下侧后，由无线充电底座13与物体进行通讯，若通讯成功，则表示物体为可无线充电电子设备，若通讯不成功，则表示物体不可被无线充电。
进一步地，物体上具有多个磁性件，磁性传感器122用于感测多个磁性件的位置；32，根据物体的位置，移动无线充电底座13至与物体的位置匹配的位置处，包括：
获取磁性传感器122感应的多个磁性件的位置；
根据多个磁性件的位置，确定物体的中心点；
移动无线充电底座13，使无线充电底座13的中心对应于物体的中心点。
控制电路11在读取了磁性传感器122的检测结果后，会根据检测结果确定待充电设备的中心位置或接收线圈的位置。在一示例中，待充电设备的四个边角处设置磁性件，控制电路11根据待充电设备的四个边角处设置磁性件的位置结合预设的算法计算出待充电设备的中心位置或接收线圈所对应的坐标，再通过获取到当前无线充电底座13的坐标后，即可以确定出无线充电底座13需要移动的距离以及移动轨迹。
34，移动无线充电底座13，使无线充电底座13的中心对应于物体的中心点，包括：
根据物体的中心点，确定无线充电底座13所要移动的纵向移动距离以及横向移动距离；

根据无线充电底座13的纵向移动距离以及沿纵向移动的预设速度，确定无线充电底座13沿纵向移动的第一时长；
根据无线充电底座13的横向移动距离以及沿横向移动的预设速度，确定无线充电底座13沿横向移动的第二时长；

具体的，首先计算无线充电底座13所要移动至的位置横向坐标与无线充电底座13当前位置的横向坐标的差值，再利用该差值与第一预设速度的比 值，从而计算出第一导轨141需要沿沿第二导轨142以第一预设速度移动的第一时长。进而计算无线充电底座13所要移动至的位置纵向坐标与无线充电底座13当前位置的纵向坐标的差值，再利用该差值与第二预设速度的比值，从而计算出第一导轨141需要沿第二导轨142以第二预设速度移动的第二时长。在此第一预设速度和第二预设速度可以为相同的值，也可以为不同的值。
